This invention relates to remote controls for selective automatic.phonographs, and has for its primary object to' provide an improvedremote control whereby any desired selection or a plurality ofselections may be paid for and selected at a remote position withrespect to the phonograph.

A further object of the invention is to provide aremote control adaptedto select recordings to be played and adapted to put the phonograph intooperation by means of radio frequency impulses.

A further object of the invention is to provide an improved remotecontrol for phonographs having an improved switching mechanism, wherebyan appropriate number of impulses of radio frequency may be transmittedcorrespond ing to the recording selected.

after each record is played and is latched out The escapement member I8carries an armature Other objects, advantages and capabilities of theinvention will appear from the following description of a preferredembodiment thereof, taken in conjunction with the accompanying drawingsin which:

Fig, 1 is an elevational view of a phonograph adapted to be controlledby my remote control;

Fig. 2 is a diagrammatic view and wiring diagram of my improved controlelements on the phonograph;

Fig. 3 is a similar diagrammatic view and wiring diagram of a controlunit;

Fig. 4 is a diagrammatic plan view showing elements of my remote controlunit; and

Fig. 5 is an elevation of the clockwork and associated mechanism of Fig.3, as viewed from the lower side of that figure.

Referring to the drawings, the improved remote control is illustrated inconnection with the multi-selective automatic phonograph known and'extensively sold throughout the country as the Symphonola, thephonograph being manufactured by J. P. Seeburg Corporation of Chicago.It will be understood, however, that the invention may be applied toother well-known The automatic phonograph shown in the drawings is sowell known that it need not be. described in detail. It is sufficient tonote that it comprises a plurality of manually operable selector leversIt], a motor H, and a main switch 12. When the main switch I2 is closed,the motor operates and the record changing cycle becomes operative. Itmay be noted that the record changing operations, and the accompanyingactuationof the turntable (not shown) and the a record. Means'areprovided, adapted to cooperate with the selector levers it, so that therecord corresponding to an actuated selector lever I0 is moved out andplayed when the motor II is put into operation.

The main switch I2 is normally open, being maintained in open positionby .means of a pin IE on a ratchet wheel l6. lThe ratchet wheel I6 isbiased away from switch closing position of the pin l5 by means of aspring 41. An escapement member I8, mounted on a pivot 59, is arrangedto co-operate with the ratchet wheel I8.

20, which is adapted to be attracted by an electromagnet 2i. energizedmomentarily, the escapement member l8 is oscillated so that the springI} may move the ratchet wheel through ,a distance corresponding to onetooth. This movement of the ratchet wheel'withdraws the pin 85 from themain switch l2 so that this switch closes. The closing of the mainswitch sets the motor in operation. If the electromagnet 2| is energizeda plurality oi'ttimes, then the ratchet wheel I6 is moved by the springI1 through a distance corresponding to a similar number of teeth. Thecam shaft 14 carries an arm 22 upon which is pivotally mounted a strikermember 23. This striker member co-operates with a stationary anvil 24.The arrangement is such that after a record has been played, the strikermember 23 is moved by the cam shaft 14 until it clears the anvil 24,whereupon the striker member, under influence of the spring 25, strikesthe ratchet wheel l6 and returns it toward initial position through adistance corresponding to onetooth on the ratchet wheel.

It is to be understood that if a certain number, for example three,selector levers Ill are depressed and the electro-magnet 2| is energizedthree times, then the phonograph will be put into operation so asautomatically to play the three records corresponding to the threeselector levers. When the playing of the third record is finished, themain switch I2 opens and the opplayer arm l3, are performed by arotation of operator to perform these operations from any When theelectromagnet 2| is practical position desired, and in any degree ofremoteness from the phonograph.

The mechanism upon the phonograph provided for the purposes of myinvention comprises a radio receiver 26, which is tuned for reception ofa definite radio frequency. The receiver 26 is provided with an antenna21. The receiver may be of any desired internal construction, it beingmerely necessaryto provide an output adapted to close a switch 28 eachtime that an impulse of the aforesaid radio frequency is received by theantenna 21. The switch 28 is in series with the battery 23 and with asolenoid 30. The armature of the solenoid is'connected to a slidablymounted member 3|, which carries a dog 32,

which is biased towards a ratchet wheel 33. The

member 3| is biased away from the solenoid by a spring 34. It will benoted that when the sole noid 30 is energized, the member 3| movestowards it, the dog 32 slipping past the teeth of the ratchet. wheel 33.When the solenoid 30 is tie-energized, the spring 34 moves the member 3|away from the solenoid and its dog moves the ratchet wheel 33 one tooth.

The ratchet wheel 33 rigidly carries a wiper arm 35, which is adapted toengage an arcuate series of contacts 36 during the rotation of theratchet wheel 33. The ratchet wheel 33 and wiper arm 35 are biasedtowards the zero position of the wiper arm by means of a spring 31. Thisposition is determined by suitable stops 38, one of which is stationary,the other being mounted on the ratchet wheel. The contacts 36 correspondin number to the number of selections for which the phonograph isadapted. In the present case that number is twenty. These contacts arear-v ably mounted member 3| is moved towards it, an

abutment 39 engages an arm 40 and displaces it to its full-lineposition'in Fig. 2, tensio'ning the spring 68, which drives delayclockworkmeclianism 4| during the return of the arm 40. This arm 40 ismounted on, and operatively connected to, the clockwork mechanism 4|.The arm 40 is connected to this clockwork mechanism by means of aslipping clutch (notshown) ,which may be of any suitable known type, theconnection being such that the arm 40 may be moved towards the solenoid30 without aflecting the clockwork mechanism, but it reverse movement isdelayed and made gradualby its'operative connection to the clockworkmechanism. Consequently, the arm 48 is moved to the left (Fig. 2) by theabutment 33 rapidly, but its return is relatively slow and gradual. Whenthe solenoid 30 is energized in rapid succession, the arm 40 is arm 40is elevated out of contactwith the do 42 during the series ofenergizations, and the dog 32 moves the ratchet wheel 33 through adistance corresponding to five teeth thereon and moves the wiper arminto engagement with the fifth contact 36. The dog 42 holds the ratchetwheel 33 and the wiper arm 35 in this position until the clockworkmechanism 4| returns the arm into a position in which it actuates thedog 42 and removes it from the ratchet wheel 33. Just before thedog42isdisengaged from the ratchet wheel 33, an insulated arm 44,rigidly connected to the arm 40, makes engagement with a stationarycontact 45. After this contact is made and after the clockwork mechanism4| moves the arm clear of the stationary contact 45, the dog 42 isremoved out of engagement with the ratchet wheel 33 so that the ratchetwheel 33 and the wiper arm 35 return to normal or initial position.

Each contact 36 is connected to an individual solenoid. 46 arranged forco-operation With the corresponding selector lever I0. These solenoids46 are connected to a common wire 41. This wire is connected to theelectromagnet 2|, the other side of this magnet being connected by aconductor 48 to the arm 44. One side of the battery is connected by aconductor 43 to the stationary contact 45. The other side of the batteryis connected to the wiper arm 35 by conductor 50.

Each solenoid 46 is provided with an armature 5|, which is biasedupwardly by a spring 52. Each armature 5| is connected to a hook member53,

which is adapted to overhang the corresponding selector lever Hi. Itwill be understood that when a solenoid 46 is energized, its armature 5|moves downwardly against the action of the spring 52, and that the hookmember 53 engages the corresponding selector lever III and moves itdownwardly. When the solenoid 46 is deenergized, the

40 spring 52 moves the armature 5| and the hook maintained at itshighest position until the series of energizations ceases.

When the arm 40 is in its normal position, it'

engages a dog 42 so as'to hold this dog out of engagement with theratchet wheel- 33. The dog 42 is biased toward the ratchet wheel 33 by aI member 53 upwardly so that the selector lever It may be returned toinitial position by the automatic operation of the phonograph.

The operation of the mechanism described above is as follows: When thereceiver 26 receives a certain number of impulses, for example fiveimpulses of the appropriate radio frequency, the switch 28 clo'sesmomentarily five times. The solenoid 30 is energized five times. On thefirst energization of the solenoid 30, the arm 40 moves towards it andthe arm 44 is moved past the stationary contact 45. It is to be notedthat the engagement between the arm 44 and the contact 45 has no efiectbecause the wiper arm 35 is in zero position and out of engagement withall the contacts 36. During the series of actuations of the solenoid 30,the arm 4|| remains substantially in the position shown in Fig. 2. Thefive actuations of the solenoid 30 move the wiper arm 35 step by stepuntil it is in engagement with the fifth contact 36, the dog 42 beingrendered operative upon the first movement of the sliding member 3| tothe left. "The actuations of the solenoid 33 having ceased, the arin 40returns relatively slowly towards its initial position, bringing the arm44 into engagement with the stationary contact 45.

A circuit is now completed from the battery 23,-through conductor 50,wiper arm 35, the fifth contact 36, the corresponding solenoid 46,conductor 41, electromagnet 2|, conductor 48, arm 44, stationary contact45, and conductor 49. Thus, the' corresponding selector lever, that is,the fifth selector lever III, is displaced downwardly and the ratchetwheel I6 is moved into posiwill now move out and play record numberfive. After this record is played, the cam shaft I4 is put intooperation and the striker member 23 returns the ratchet wheel I 6 toinitial position, thus opening the switch I! and bringing the operationof the phonograph to an end.

If, during the playing of the fifth record, another series of impulses,for example three impulses, were received by the receiver 26, the thirdsolenoid 46 would be energized and the third selector lever It would bedisplaced downwardly, and at the same time the electromagnet would bemomentarily energized. In this event, the completion of the playing ofthe fifth record would not stop the phonograph. The fifth record wouldbe returned to the stack and the third record would be moved out andplayed. It will be understood that the actuation of the ratchet wheel l6by the striker member 23, after the playing of the fifth record, wouldnot open the switch, since the two actuations of the escapement memberi8 resulting from the two series of impulses would have moved theratchet wheel it two spaces away from switch closing position. Ofcourse, it will be understood that any number of, or all of, the twentyselections may be selected and played before the phonograph stops.

It. will be understood that the series of impulses referred to above andwhich actuate the mechanism previously described are produced by one orindeed any number of remote control units, the structure and operationof whichv will now be described.

My improved remote control unit may suitably be contained within ahousing. (not shown) which is provided with a coin chute 54, .whichchute is provided with a switch 55 which is adapted to be closed, inknown manner, by an inserted coin.

-One side of this switch is connected to a battery 56, the other sidebeing connected to a solenoid The solenoid 51 is connected to the otherside of the battery 56 so that the solenoid 51 is energized each time acoin of the appropriate denomination is inserted in the coin switch as.My remote unit is provided with a series of buttons 58 correspondinginnumber to the number of selections for which the phonograph isarranged. These buttons are available to the operator, projectingthrough the wall of the housing. Each button '58 is mounted on a rod 59,mounted within the housing for axial movement. Each rod is 'tion to openthe switch l2. The phonograph sleeve 84 is provided with a left-handabutment 66 and a right-hand abutmenti'l. It is to be noted that thefirst sleeve 64 need not be provided with a left-hand abutment and thatthe last or twentieth sleeve 64 need not be provided with a right-handabutment.

Each left-hand abutment 66 is located immediately in front of and inoverlapping relation to the right-hand abutment of the sleeve Elimmediately to the left. Consequently, when one button is pushed in, itssleeve 68 is moved rearwardly and all the sleeves to the left of theactuated sleeve are moved rearwardly so that the switch 65 correspondingto the actuated button is closed, and all the switches 65- to the leftof that actuated sleeve are closed. All the sleeves to the right of theactuated sleeve remainin their normal position and their switches remainopen. The sleeves 64 are biased forwardly by weak pressure, which may besuppled, for example, by

the adjacent leaves of the switches 65. Consequently, the sleeves 64 arereturned to normal position and their switches 65 are opened when thebar 62 is again raised. For'the sake of simplicity, it may be noted thatif button number five is pressed inwardly, then the first five switches65 on the left are closed, the other switches 65 remaining open. Theswitches 55 have one side connected in series and to one side of thebattery. The other side of the battery is connected to a transmitter 69.The other sides of the switches 65 are connected individually to anarcuate series of contacts 10, these contacts, of

course, corresponding in number to the number of records inthe'phonograph, in the present case twenty.

The contacts it are adapted to be engaged by a wiper arm 1 l, whichnormally occupies a zero position beyond the contacts. When the wiperarm TI i in normal position, it engages a rocker arm 12, which controlsthe switch l3, this switch being open when the wiper arm H is in normalposi*- tion. The wiper arm ii is mounted on a shaft 14, which is biasedto the initial position of the wiper arm by means of a spring ti coiledaround the shaft. The shaft idcarries a gear 15, which is in mesh withthe quadrant it. This quadrant biased outwardly by a spring 80 and eachis provided with an annular projection 6|. A fingered bar 62, which ispressed downwardly by a spring 63, is adapted to co-operate with theannular projections ti. when one of the buttons 58 is pressed inwardly;this annular projection 5i raises the bar 62 against the action of itsspring Consequently, any other rod 59 and button 58, which may have beenpressed inwardly, is 1'6:

When the annular projection 6| of the button now being pressed inwardlymoves behind thebar 62, the bar descends and holds the button in itsleased and moved outwardly by t spring, as

inward position until another button is pressed.

inwardly.

Upon the inner end of each rod 59 is mounted a sleeve 64 of insulatingmaterial, the innermost end of the sleeve being closed. The innermost toone side of the switch 73.

is pivotally mounted and carries a projecting arm Ti, which is pivotallyconnected to the armature- 18 of the solenoid 51. It will thus be seenthat when the solenoid 5? is energized, its armature it moves upwardlyand the quadrant it moves downwardly, rotating the wiper arm inclockwise direction past and beyond all the contacts. After the arm Hhas passed the contacts, it engages the rocker arm 72 and moves it tothe left, closing the switch 73. The shaft is is connected to theclockwork mechanism 79 by a slipping clutch (not shown), so that theclockwork mechanism is unaffected when the arm ii is swung around inback in counterclockwise direction, under the influence of its tensionspring 86, the clockwork mechanism is actuated and serves as. a delaymeans so that the return ofthe wiper arm H is relatively slow. Thetransmitter 69 is connected The other side of the switch is connected tothe wiper arm H. When the switch '73 is closed and the Wiper arm ll isreturning to initial position, the transmitter control circuit iscompleted through the battery, through each closed switch 65 and throughthe corresponding contacts Hi, the wiper arm H, and the switch 13.Consequently, during the return of the wiper arm H the control graphstops.

circuit of the transmitter 69 is closed a number of times, correspondingto the number of the button 58 which has been actuated. The transmitter69 is provided with a transmitting antenna, 80, and it is arranged totransmit an impulse of radio frequency energy each time that its controlcircuit is completed. Consequently, during the return movement of thewiper arm II, a series of impulses of radio frequency energy aretransmitted by the antenna 80, corresponding in, number to the number ofthebutton 58 which has been actuated. It is, of course, to be understoodthat the transmitter 69 is tuned to transmit the same radio frequencyfor which the receiver 26 is tuned.

The operation is as follows: Assuming that the operator desires to playrecord number five, he pushes button number five, thus mechanicallyclosing the first five switches 65. Then he inserts a coin of suitabledenomination in the chute 54, thereby closing the switch 55 andenergizing the solenoid 51. The energization of the solenoid swings thewiper arm from its initial position in clockwise direction past all of.the contacts Ill. It

"is to be noted that the engagement of the wiper phonograph, a remotecontrol unit therefor, said remote control unit comprising a series ofswitches, each corresponding to a record in the phonograph, manuallyactuated means corresponding to and adaptedto close said switch, andmechanical means connecting said manually actuated means wherebyactuation of one of said manually actuated means actuates thecorresponding means and all the preceding means of the series to closethe corresponding and all preceding switches of the series, an arcuateseries of contacts each connected to one of said switches, a wiper armadapted to move over said contacts, a circuit including said actuatedswitches and said wiper arm, a radio frequency transmitter connected tosaid circuit and adapted to transmit an impulse of radio frequency eachtime the wiper arm engages a connected contact to complete said circuit,a receiver at the phonograph adapted to receive said impulses,

arm movable by said relay to various positions depending upon the numberof impulses received by the receiver, electromagnetic means on thephonograph individual to each recording, and

The circuitis not 1 with the result that the motor II is started and the fifthselector lever I0 is moved downwardly so that record number five ismoved out and playedin the manner described above. If, during theplaying of record number five, another button 58, for example, the thirdbutton, is actuated and a coin is inserted in the chute 54,threeimpulses will be transmitted and the third selector lever I0 ismoved downwardly. At the same time, the ratchet wheel I6 is movedthrough the distance of another tooth away from its initial position sothat both records will be played before the phonograph stops. It will beobvious that any desired number of records may be selected in thismanner.

It will be understood that any desired number of remote control unitsmay be provided and operated in this manner in connection with a singlephonograph unit, all the records selected by all the operators beingreproduced before the phono- The phonograph can, of course, be put intooperation by actuation of any of the remote control units.
